Acknowledgments

Most of the work creating and advancing PUMAS is volunteered by professional scientists and other content experts, software developers, and teachers.

PUMAS Examples of the Practical Uses of Math And Science are contributed by the authors for the benefit of pre-college science education. We thank them, and those who post comments and activities/lesson plans relating to individual examples. Their names appear with their contributions.

We also thank those who volunteer to serve as Reviewers. The names of PUMAS reviewers are listed at the bottom of this page.

PUMAS was conceived by Ralph Kahn and developed under his direction. For the PUMAS Web Site, Ralph Kahn wrote the texts,
Jason LaPointe developed the original software (1996-1997), Cecelia Lawshe performed the first full redesign and upgrade of the underlying software in 2003, and Paul Przyborski performed the second design and software upgrade in 2008. Lena F. Kahn and Harman Smith designed the graphics, which was digitally rendered by Harman Smith.

Since June 2008, the PUMAS Journal is maintained the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center. From 1996 to 2008, PUMAS was produced and maintained at the Jet Propulsion Laboratory / California Institute of Technology (JPL/Caltech), under contract with NASA. PUMAS activities are supported in part by the Earth Science and Applications Division and the Education Division of NASA, by the Education Offices at the NASA Goddard Space Flight Center and JPL/Caltech, and primarily by the volunteers who contribute content and advice to this journal.

Many people have contributed to PUMAS. For helping the Journal through its early development stages, we thank:
